When you are ready to activate the animation click the start button in the
animation rectangle.

When the animation begins notice what is happening to the particles. You should
also notice what is happening to the temperature of the system as indicated
by the thermometer. When the temperature stops changing click the mouse on the
Continue button and the animation will continue. When the animation finally
stops answer the questions. It is OK to view the animation more than once, just
click on the Repeat button.

Important do not press the enter key or the Return key
while you are answering these questions. Your Browser will interpret either
key the same as clicking the mouse on the Submit button. So BE CAREFUL!

Give me some responses to the questions below and I'll give you some extra
credit.
